Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection [PDF]
Advanced ScienceCherenkov radiation enables high‐energy particle identification through its velocity‐dependent emission angle, yet conventional detectors fail to detect momenta beyond tens of GeV/c owing to the absence of natural materials with near‐unity refractive ...

Reverse surface-polariton cherenkov radiation. [PDF]
Sci Rep, 2016 AbstractThe existence of reverse Cherenkov radiation for surface plasmons is demonstrated analytically. It is shown that in a metal-insulator-metal (MIM) waveguide, surface plasmon polaritons (SPPs) excited by an electron moving at a speed higher than the phase velocity of SPPs can generate Cherenkov radiation, which can be switched from forward to ...

Coherent Cherenkov Radiation by Bunches in Fast Radio Bursts [PDF]
Astrophysical Journal, 2023 Fast radio bursts (FRBs) are extragalactic radio transients with extremely high brightness temperature, which strongly suggests the presence of coherent emission mechanisms.

On-chip Cherenkov radiation tuning in 3.2-14 THz [PDF]
Nature CommunicationsCherenkov radiation has attracted much attention for promoting the free electron radiation sources. Using hyperbolic metamaterial, Cherenkov radiation can be excited using low-energy electrons and thus on-chip free electron radiation source has been ...

Transient Cherenkov radiation from an inhomogeneous string excited by an ultrashort laser pulse at superluminal velocity [PDF]
, 2014 An optical response of one-dimensional string made of dipoles with a periodically varying density excited by a spot of light moving along the string at the superluminal (sub-luminal) velocity is theoretically studied.

Dispersive 2D Cherenkov radiation on a dielectric nano-film [PDF]
Scientific Reports, 2017 We report a modified two-dimensional Cherenkov radiation, which occurs on a high-index dielectric nano-film driven by uniformly moving electron-beam. It is essentially different from the ordinary Cherenkov radiation in that, in the nondispersive medium ...

Backward Cherenkov radiation emitted by polariton solitons in a microcavity wire [PDF]
Nature Communications, 2017 Cherenkov radiation is generated from fast electrons and its optical analogue plays an important role in many nonlinear optical effects. Here, Skryabin et al.

TOF-PET Image Reconstruction With Multiple Timing Kernels Applied on Cherenkov Radiation in BGO. [PDF]
IEEE Trans Radiat Plasma Med Sci, 2020 Today Time-of-Flight (TOF), in PET scanners, assumes a single, well-defined timing resolution for all events. However, recent BGO–Cherenkov detectors, combining prompt Cherenkov emission and the typical BGO scintillation, can sort events into multiple ...

On Tamm's problem in the Vavilov-Cherenkov radiation theory [PDF]
, 1999 We analyse the well-known Tamm problem treating the charge motion on a finite space interval with the velocity exceeding light velocity in medium. By comparing Tamm's formulae with the exact ones we prove that former do not properly describe Cherenkov ...
